APD 1080 & 1090 Series DC Input Alarms

The APD 1080 and APD 1090 accept a DC voltage or current input and provide visual alarm indication and alarm relay contact outputs. 15 voltage and 9 current input ranges can be field-configured via external rotary and slide switches. Offset ranges such as 1-5 VDC and 4-20 mADC are also included. Heavy-duty relay contacts allow the module to directly control high capacity loads. Front-accessible potentiometers are used to adjust the alarm setpoint from 0 to 100% and the deadband from 1 to 100%.

The APD 1080 provides a single setpoint adjustment of the two DPST relay contacts. The alarm output can be field configured for HI or LO operation, latching or non- latching, and normal or reverse acting.

The APD 1090 provides two setpoint adjustments of the two DPST relay contacts. The alarm outputs can be configured in the field for HI/HI, LO/LO, HI/LO or LO/HI operation, latching or non-latching, and normal or reverse acting. Deadband and alarm setpoints are independently adjustable for each alarm.
